6Claims. (01. 88-48) My invention relates to adjustment of spectacles; and particularly to adjustment of the elevation of spectacles with of the wearer.

This application Isa continuation-in-part of my earlier application for Letters Patent of the UnitedStates, Serial No. 87,754, filed June 27, 1936, for Adjustment of spectacles- Figures 1, 2, 3, 4, 5, 6, 7, 7a and 8 of. the present application correspond to Figs. 1, 2, 3, 4, 5,16, ,7, 7a and 8, respectively, of the earlier application.

One feature of my'invention is the provision of means for adjusting the elevation of bifocal spectacles for far and near vision. Another feature of my invention is the provision of means for raising, for other purposes, various types of spectacles from a first elevation to a higher elevation with relation to the eyes of the wearer.

I shall describe several forms of apparatus and a method embodying my invention, and shall reference to the eyes view in vertical section of the pad and bridge then point .out the novel features thereof in claims.

In the accompanying drawings, Fig. 1 is an en- 4 Iarged plan viewof a removable auxiliary nose pad I; Fig. 2 is an enlarged view in side elevation of the nose pad shown in Fig. 1; Fig.3 is a view .n horizontal section along the line III-III of F'ig. 2; Fig, 4 is a view in vertical section along .ine IV-IV of Fig. 1 showing also application of a. removable nose pad I to a usual or main nose Jad II; Fig. 5 is a'view showing pad I in section along center line V-V of wire 2 in Fig. 2 and ;howing a full view of wire 2; Fig. 61s an en-v arged view in side elevation of av modified form )f auxiliary removable nose pad; Fig. .7 is' a view n horizontal section along' the lineVII-VII ofv Pig. 6; Fig. 7a is a view similar to Fig. '7,' but of t modified form of the (device shownyin Fig.6;

Similar reference characters refer to similar,

parts in each .of the views.

In each of the Figs. 1, 2, 3, 4, 5 and. 8 of the drawings, a pad I is shown'which'may be formed of cloth, Celluloid, or other suitable material, from the upper end of which a loop of wire 2 projects. 'As here shown, wire 2 extends to the lower end of pad I, where the ends of wire 2 may be twisted or soldered together. Otherarrangements of wire 2 in pad I may, however, be employed. The materials commonly used in nose pads for spectacles may also be among the materials which are suitable for pad I. Wire 2 may preferably be of a spring material, such, for example, as spring steel. A recess 6 is formed in pad I to receive a usual or main nose pad II, shown in Figs. 4 and 8, which is usually irremovably attached toa bridge I2 through a curved piece I6. I 1

Figs. 6 and 7 show a modified form of auxiliary removable nose pad comprising a pad 8, from which loops of wires 9 and I0 project. The form shown in Fig. 7a has a pad 8 and a wire loop 9 ,as shown inFig. 6, but has hooks I! instead of loops I0.

It may be found more convenient if. the removable pads for each-pair of spectacles are connected togethejrin pairs by some means, such for example asa string, wire, or strip. p

, A methodof'adius'ting a pair of bifocal spectacles for far and near vision consists of setting the spectacles ,"with respect to .thefmain nose pads I I, so that the spectacles are at the proper elevationfor-f farvision but are too low for comfortable or eflicient near vision-and of applying removable nose pads, such as here shown, to the two main nosepads II to-raise. the spectacles while they ar e being used. for I near vision. The

,removablenose'pad shown in Figs. 1, 2, '3, 4 and 5,'is applied byan upward push sothat a main -nose, Pad llfenters recess 6 of the removable nose EE-XI of Fig. 9; Fig. 12 is 'a view horizontal action along the line X[I'XIIiof Fig; 9; Fig.

2a is a view similar to Fig. 12, but of aimodifled arm of the pad shown in Fig. 9; Fig.13 is an'en-' trged front view of a modified form of auxiliary I amovable nose pad for use with spectacles hav- 1g bridge means contacting the top of thewe'ar f pad as shown in Figs. 4 and 8. Wire loop 2 is then pushedover the upper end of 'main'nose Dads II for retaining-the removable nose pad. In applying thenose'padjshown in Figs. 6 and 7. loopslfl are pushed up over a main nose pad II, and loop 9 isthenpushedover the upper end of theniain nose-pad] I, similarlyto the manner 7 over a main nose pad ends of loop 19 may the portion 20 of This upward movement upper end of the main nose rest II.

in which loop 2 of the device shown in Figs. 1, 2, 3,4 andliispushedover theupper endofthe main nose pad II. The device shown in Fig. 'la may be similarly applied by pushing hooks II up II and then pushing loop 9 over the upper end of pad i I.

Figs. 9, 10 and 11 show a modified form of auxiliary removable nose pad means comprising a pad is equipped witha loop 10 which may be of a spring wire material. Nichrome wire has been used satisfactorily for loop 19. The purpose of the loop II is to retain the auxiliary removable pad I! more securely on the irremovable pad or main nose rest ll, although an auxiliary removable pad of this type adheres fairly well to a main nose rest ll without such retaining means. Instead 'of a loop ll, other retaining means; such for example as a flat strip, could be used.

Pad [8 may be made of a material such as zylonite or other materials commonly used in main nose rests ll.

Pad It has a curved wedge shaped portion 20, which, when the pad is in use, is between the nasal side of a main nose rest I l and the wearer's nose, thereby serving to raise the spectacles with respect to the'eyes of the wearer. Pad I! also has a recess 21, at the lower end of which is a retaining portion 22, and at the upper end of which is a second retaining portion 23. The lateral edges of pad I. along recess 2| may also have inwardly directed portions 28 between, and similar to, but probably narrower than, the retaining portions 22 and 23 as shown in Figs. 9, 12 and 12a. Pads 18 having a wedge shaped portion with a thickness adjacent the lower end of the order of one-sixteenth inch, or slightly thicker, have been found to give good results for raising bifocal spectacles in order to bring the near seeing portion of the lenses into suitable position for near vision.

One manner of attaching loop I! to pad I. is by inserting the ends of loop 19 into the lower end of pad It as shown in Figs. 9 and 10. The be equidistant from the vertical center line of pad 18 or they may be in some other location with' respect to pad II, as

shown in Fig. 9, in order to render loop is less visible. With the ends of loop I! located as shown in Fig. 9, the pad should therefore be used on the right-hand main nose. rest II. A pad I! for use on the left-hand main nose rest I I should then have the ends of loop I! on the opposite side of the vertical center line of pad II.

The portion 20 may be of practically uniform thickness in horizontal cross section as shown in Fig. 12, or it may be found preferable to make less thickness near the top of the wearer's nose as shown in Fig. 12a.

In applying an auxiliary removable nose pad I. to a main nose rest ll of a pair of spectacles, the pad I! is first pushed upward to receive the lower end of the main nose rest H in the recess 21 beneath the upper or free portion of loop II. of pad I8 is continued until the retaining portion 23 snaps over the Pad ll may then be pushed downward slightly.

In order to remove a pad I! from a main nose rest ll, pad ll may first be pushed upward, and then its upper end pushed away from the upper end of main nose rest ll. Pad ll may then be pushed downward out of engagement with main nose rest H.

Pads 1 and it can thus be easily applied to,

'and easily removed from. main nose rests M.

This characteristic is important. since a person may not be able to see clearly with his spectacles removed while applying or removing the pads I8. Another important characteristic of the pads l and II is that they are inconspicuous, pleasing in appearance when in use on main nose rests Ii.

Figs. 13, 14, 15 and 16 show a modified form of auxiliary removable nose pad means, for use with spectacles having main nose rest means such as bridge means contacting the top of the wearer's nose, comprising a pad 24 equipped with loops 2! for more securely retaining the pad 24 on the bridge means 21 of a pair of spectacles. Pad 24 has a wedge shaped portion 26 which is between the nasal side of bridge means 21 and the nose of the wearer when pad 24 is in use with a pair of spectacles. The thicker portion of the wedge 20 is at the lower portion of pad 24. Although pad 24 is shown having a wedge shaped portion 24, such a pad could have, instead, a corresponding portion of substantially uniform thickness of sufficient magnitude for raising a pair of bifocal spectacles from an elevation suitable for far vision, without the pad 24, to an elevation suitable for near vision when pad 24 is used with the spectacles as shown in Figs. 15 and 16. Pad 24 and loops 25 can be of materials similar to the materials suggested for pad fl and loop II, respectively, of Figs. 9, 10 and 11.

Dark glass attachments when applied to bifocal spectacles and also to other spectacles, such for example as for use in driving an automobile in bright sunlight, depress the spectacles to a lower elevation with respect to the eyes of the wearer.

.Auxlliary removable nose pads, such as herein shown and described, could be used in such instances to raise the spectacles from the depressed position to the normal elevation with relation to the eyes of the wearer.

I have found that if spectacles similar to those shown in Fig. 8 are positioned, with respect to the main nose pads ll, so that the near-seeing portions I! of the lenses are low enough that they do not interfere while a wearer of the spectacles is walking along cannot read comfortably at a desk without tilting the head backward. I have if the spectacles are so to the main nose pads portions fortable and efficient near vision, they are not comfortable to the wearer while walking considerable distances. I have found too that, when driving an automobile, it is desirable to have the spectacles raised above the position which is suitable for walking considerable distances, in order II, that the near-seeing to be able to comfortably read the instruments on the instrument board. From actual use of a nose pad constructed as shown 5, 9, 10 and 11, I have spectacles, which satisfactory.

Although I have herein shown and describedonly a few forms of apparatus and one method embodying my invention, it is understood that various changes and modifications may be made therein within the scope of the appended claims without departing from the spirit and scope of my invention.
